Dozens of armed police were sent to the Hollywood home of Two And A Half Men star Kutcher after a call was received claiming people were there with guns and explosives - and several people had been shot.

Officers were also dispatched to Bieber's Los Angeles-area home after a false emergency call said gunshots had been fired on the property.

Singer and actress Miley Cyrus has also been targeted by a "swatting" prank, but police said that case had not been linked to the Kutcher and Bieber incidents.
